OILING DEVICE FOR AXLES.

SPECIFICATION forming part of Letters Patent N 0. 790,451, dated May 23,1905.

Application filed November 17, 1904:. Serial No. 233,179.

T0 at whom it may concern:

Be it known that I, CLAUDE M. MOFARLAND, a citizen of the United States,and a resident of South St. Joseph, Buchanan county, and State ofMissouri, have invented certain new and useful Improvements in OilingDevices for Axles, of which the following is a specification.

The presentinvention relates to an improvement in lubricating devicesfor car-axle jour-' nals, and has for its object to provide a simple anddurable means for effectively lubricating such journals.

' 1n the accompanying drawings, Figure 1 is -a suitable opening formedin the rear wall of the journal-box 2. This box differs from the boxesheretofore commonly employed in that its outer end is closed by aswinging door 3, the dimensions and form of which are such that when thedoor is swung into the position shown in Fig. 2 the entire outer end ofthe box is opened.

A removable lubricant-receptacle 4 is adapted to be inserted in the boxthrough the opening at the outer end thereof when the door 3 is in theposition shown in Fig. 2, said receptacle being preferably supported onribs or projections 5, rising from the bottom of the box. As shown, thereceptacle 4-.is preferably provided with side walls of such height asto extend above the horizontal plane of the lower face of the journal'l,recesses 6 being formed in the end walls of said receptacle, throughwhich the journal can extend.

A wick-support comprising two parallel rollers 7 and an intermediateconcave plate 8 are detachably mounted within the receptacle 4:, therollers being so arranged as to lie on opposite sides of-the verticalplane, including the axis of the journal, when said receptacle is withinthe box 2. As shown, said wicksupport is mounted in suitable bearingsformed in the free ends of inwardly-extending arms 9 of spring-brackets,which have vertical members extending into guides formed at the cornersof the receptacle 4:. Said guides are formed by angle-plates bent toprovide flat sections 10 11, adapted to be secured, respectively,against the end and side walls of the receptacle 4, the adjacent ends ofsaid plates or sections being connected by a curved portion 12'. Each ofthe aforesaid spring-brackets may be formed from a single piece ofspring-wire coiled or bent upon itself at an intermediate point toprovide the two arms which extend substantially at right angles to eachother. vided with suitable barbs or spurs 13, which engage the body ofthe endless wick 15,- and each roller is provided at its outer end witha head or enlargement 16, by means of which the roller can be rotated inits bearings to move the wick transversely of the journal 1.

The wick is preferably of such length as to extend from the supporttherefor substantially to the bottom of the receptacle 4 and into theliquid lubricant placed within such receptacle. Such lubricant will bycapillary attraction be conducted upwardly to the portion of the wick onwhichthe journal bears. If at any time it is desired to bring anotherportion of the wick beneath the journal, the rollers 7 can be readilyrotated, the heads 16 lying outside of the receptacle 4:, as shown inFig. -l.

A dust-guard 17, consisting of two telescoping sections, is arrangedabout the journal in rear of the lubricating device, the members of suchguard being pressed sufficiently close upon the journal to prevent theentrance of dust by means of springs 18,

The operation and ad vantage of the lubricating device herein describedwill be apparent. It will be seen that the invention provides arelatively large lubricating-surface for the journal, extendingpractically throughout the length thereof, and that if for any reasonone section of the wick becomes un- As shown, the rollers 7 are pr0suited for use by turning the roller 7 a fresh surface can be broughtinto operative position. The entire lubricating device can be readilyremoved from the box 2, and by making such box in the manner illustratedand described it is possible to use a receptacle adapted to contain arelatively large amount on said frame on opposite sides of the verticalplane of the axis of said journal, and provided with means whereby theycan be rotated in said bearings independent of any movement of thejournal and while in operative position relative to the journal, and awick extending over and engaging said rollers.

2. The combination with a car-axle journalbox, having an opening at oneend, and means for closing said opening, of a lubricant-receptacleadapted to be removably inserted in the box through said open end, anendless Wick supported by and extending into said receptacle and adaptedwhen said receptacle is in position in the axle-box to bear against theunder surface of the axle-journal, and means independent of theaxle-journal for moving said Wick to bring any desired portion thereofinto contact with the journal.

3. The combination with a car-axle journalbox, of a lubricant-receptacleadapted to be removably inserted in the box, yielding frames supportedadjacent the ends of said receptacle, a rotatable wick-support mountedin bearings in said frames, and an endless wick extending over saidsupport and into the receptacle on opposite sides of said support.

4. The combination with a car-axle journalbox, of a lubricant-receptacleadapted to be removably inserted in the box through an opening in an endwall thereof, a wick-support comprising two parallel rollers and anintermediate concave plate, means for detachably connecting said supportto the lubricant-receptacle to bring the concave plate thereof beneaththe axle-journal when said receptacle is in position within the box, andan endless wick carried by said wick-support and extending across theupper face of said concave plate and into the receptacle on oppositesides of said support.

5. The combination with an axle-journal, of a box having in its rearwall an opening through which said axle-journal extends and having itsfront wall formed by a swinging door, a dust-guard arranged within saidbox to close the portion of the opening in the rear wall thereof aboutsaid journal, a lubricantreceptacle adapted to be removably inserted inthe box through the opening at the front end thereof, an endless wicksupported within said receptacle in position to contact with the lowersurface of the journal, and means for rotating said wick to bring anydesired portion thereof into contact with the journal.

6. The combination with a car-axle journalbox, of a lubricant-receptacleadapted to be removably inserted in the box, a wick-support comprisingtwo parallel rollers, spring-arms mounted in holders secured to theinner faces of the walls of said lubricant-rece itacle and having attheir free ends bearings for said rollers and an endless wick extendingover said rollers.

7. The combination with a car-axle journal and a box for said journaladapted to contain liquid lubricant, of two rollers supported withinsaid box, means arranged between the free end of the journal and thefront of the box for rotating said rollers, and a wick extending oversaid rollers and below the same into the lubricant-containing portion ofthe box.

8. In a car-axle lubricating device, the combination ofalubricant-receptacle adapted to be removably inserted in a car-axlebox, a pair of arms extending inwardly from each of the side walls ofsaid receptacle, rollersjournaled in hearings on said arms, and a wickextending over said rollers and below the same into saidlubricant-receptacle.

9. In a car-axle lubricating device, the combination of alubricant-reeeptacle adapted to be removably inserted in a car-axle box,arms supported by the side walls of said receptacle and each formed of asingle piece bent upon itself to provide at its upper end asubstantially horizontal spring-arm that extends inwardly from the wallof the lubricant-receptacle by which it is supported, rollers mounted inbearings near the free ends of said horizontal arms, and a wickextending over said rollers and below the same into thelubricantreceptacle.

In testimony whereof] have signed my name to this specification in thepresence of two subscribing witnesses.
